To describe the sound of boxes is always such a thing. On the one hand, each other listening preferences, and secondly, it comes naturally to the sound source and the concrete spatial environment and so on. Nevertheless, I want to warn against the devil boxes. I had operated as a shelf stereo speakers on a Yamaha-middle-class amplifier. For positives: For the size of the boxes have a really rich bass. However, the treble mix to a sonic mush, which anyway spoils my listening sustainable. I then the Polk RTi A1 (also reviewed) right next to the 20 Mk2 powered and can therefore be ruled out that the site of this sound effect is crucial. Even with bass-heavy music styles spoil a the vernuschelten heights duly fun. It may be that I caught a Monday device, but another reviewer reported the same problem. All in all not bad speaker, but for my purposes useless. Those who value clean highs, should stay away from the 20 Mk2.
